The footage was caught on camera and posted on YouTube by a channel called Para Truthers in January 2015.

Their description of the video reads: “Grey Alien caught on camera January 2015 in Salford, UK.

“Look how it walks! This is definitely a real alien, it’s way too tall and skinny to be a regular person and it’s skin appears wet like a snakes skin. This is definitely the rare ‘tall white’ type of Grey.

“Never before sighted in the UK. WHY ARE THEY HERE? WHAT ARE THEY DOING?”

The account, which claims it was recently shut down by the Government - although it does not say which one - has posted several sightings of these ‘Grey Aliens’ similar to the one in this video.

While some reaction to the video has been sceptical, one YouTube user who claims to live in Salford is concerned about the possibility of life from other planets being spotted in the area.

Is it a bird, is it a plane? Or is that a UFO hovering over Strangeways?

Brights orbs seen over Stretford

The intensely bright orbs, the colour of the setting sun, were spotted by dozens of residents between 10 and 11pm.

Motorists stopped their cars and neighbours on several streets congregated outside to watch the orbs pass slowly overhead.

Some took mobile phone videos and photos of the strange lights, while others reported the sightings to Greater Manchester Police who sent two officers to investigate.

Unusual object in the sky over Eccles

In 2005 Peter Sotomski and four of his colleagues spotted the unusual object at 10am on July 10 2005.

Above them, on Half Edge Lane, Eccles, they saw the object travel across the sky at great speed, followed five minutes later by another extra-terrestrial entity.

Packed plane's close encounter with UFO

In 1995 60 passengers had no idea how close they were to a potential alien encounter.

A few years ago the government released details of a transcript between captain Roger Willis' and Manchester air traffic control in January 1995, when he claimed his Boeing 747 containing 60 passengers on route from Milan to Manchester was overtaken at high-speed by a wedge-shaped craft with bright lights.

The incident was later reported by Captain Willis and his co-pilot as a 'near miss' but files reveal the Ministry of Defence quickly dropped an investigation as it could not substantiate the report.

The clip was uploaded to YouTube earlier today and was allegedly shot in Manchester on Sunday night.

It was shared by a user named Chebbers Deighton.

He wrote that he spotted the flying saucer when he was looking out of the window at his uncle’s house, adding: “Aliens have been coming round this way for ages, mucking about and doing there dodgy stuff.

“It’s defo an invasion, I would get the council to sort it out but I reckon they are [sic] in on it working with the space men!”

However, many viewers were quick to comment on the poor quality of the video.
